Parameters

pen	The pen defining the color of the text label.

getPen()

const Pen& CDPL::Vis::TextLabelPrimitive2D::getPen

(

)

const

Returns the pen defining the color of the text label.

Returns

The pen defining the color of the text label.

setFont()

void CDPL::Vis::TextLabelPrimitive2D::setFont

(

const Font &

font

)

The font of the text label.

clone()

GraphicsPrimitive2D::SharedPointer CDPL::Vis::TextLabelPrimitive2D::clone ( ) const

virtual

Creates a dynamically allocated copy of the graphics primitive.

Returns

The copy of the graphics primitive.

Implements CDPL::Vis::GraphicsPrimitive2D.

getBounds()

void CDPL::Vis::TextLabelPrimitive2D::getBounds ( Rectangle2D &  bounds, FontMetrics *  font_metrics  ) const

virtual

Calculates the bounds of the graphics primitive.

Parameters

bounds	The object storing the calculated bounding box.
font_metrics	The font metrics object to use for bounds calculation (if required).

Implements CDPL::Vis::GraphicsPrimitive2D.
